Yesterday marked the 15th anniversary of the release of id Software's Quake II. The sci-fi first person shooter featured a single player storyline revolving around the exploits of a space marine facing off against the deadly Strogg, while the multiplayer action entertained players long after the completion of the single player campaign.

One of the original suggested names for QUAKE II was WOR, but the game’s fast-paced, tactile feel felt closer to a QUAKE game than a new franchise.

‘The Edge’ (Tim’s favorite deathmatch level in QUAKE II or any other game), has over 50 trick jumps possible in the map. Tim only designed two of them, and the rest were discovered by the QUAKE II community.
